Antony Flew's ?A Strong Programme for the Sociology of Belief (Inquiry 25 {1982], 365?78) critically assesses the strong programme in the sociology of knowledge defended in David Bloor's Knowledge and Social Imagery. I argue that Flew's rejection of the epistemological relativism evident in Bloor's work begs the question against the relativist and ignores Bloor's focus on the social relativity of mathematical knowledge. Bloor attempts to establish such relativity via a sociological analysis of Frege's theory of number. But this analysis only (...) succeeds if the rejection of an explanatory theory entails that there are reasonable grounds for the rejection of the set of propositions which that theory was intended to explain. I argue against such an entailment, and thus against Bloor's attempt to relativize mathematical knowledge. (shrink)

This is a careful explication of and commentary on Wilfrid Sellars's classic essay "Empiricism and the Philosophy of Mind" [EPM]. It is appropriate for upper-level undergraduates and beyond. The full text of EPM is included in the volume.

, David Bloor suggests that logical reasoning is radically relativistic in the sense that there are incompatible ways of reasoning logically, and no culturally transcendent rules of correct logical inference exist which could allow for adjudication of these different ways of reasoning. Bloor cites an example of reasoning used by the Azande as an illustration of such logical relativism. A close analysis of this reasoning reveals that the Azande's logic is in fact impeccably Aristotelian. I argue that the conclusions Bloor (...) can legitimately draw from his case study are not controversial and do nothing to make plausible the thesis of logical relativism. (shrink)

Bernard Gert argues that, while the moral system contains a procedure for resolving most moral disagreements, it does not allow for such resolution in all cases. For example, it does not allow for the resolution of disputes about whether animals and human fetuses should be included within the scope of those to whom the moral rules apply. I agree with Gert that not all moral debates can be resolved, but I believe that Gert does not use all the argumentative resources (...) available to philosophers to resolve them. I argue that considerations outside the moral system proper can be used to provide argumentative support favoring some positions over their rivals in moral controversies that Gert regards as intractable. I illustrate this with reference to the abortion debate. I also argue that reaching such conclusions about the superiority of one position over rivals need not result in moral arrogance. (shrink)

A striking empirical finding about color perception is that normal perceivers disagree about which hues are pure. (Pure hues contain no perceived admixture of any other color.) This finding poses a prima facie problem for color objectivism and representationalist accounts of perceptual experience. Michael Tye attempts to resolve this problem by arguing that pure hues do exist as objective properties of ordinary objects, but that human color detection mechanisms did not evolve with sufficient refinement to allow us to determine which (...) hues are the pure ones. I argue that Tye’s attempted solution fails, and that the most reasonable conclusion consistent with color objectivism is that pure hues do not exist. (shrink)

In a previous issue of this journal, Michael Hicks challenges my critique of Wilfrid Sellars’s arguments against the given and against the foundationalist epistemology that relies on the idea of a sensory given. I had argued that Sellars’s well-known claim that the given is a myth does not succeed because at a critical juncture he misconstrued sense-datum theorists such as Bertrand Russell and H. H. Price. In his response to my argument, Hicks makes the striking claim that Sellars was not (...) targeting foundationalism at all in his discussion of the myth of the given. Hicks reconstructs a key argument in “Empiricism and the Philosophy of Mind” (EPM) in a way intended both to avoid any reference to foundationalism and to do a more effective job than does Sellars’s original argument in uncovering a dilemma for traditional empiricism. The present paper challenges Hicks on two fronts. First, it argues that Hicks’s reconstruction is not more successful than Sellars’s original argument. Second, a review of relevant passages in makes clear that the critique of foundationalism is a prominent aspect of Sellars’s multi-faceted attack on the given. The conclusion reasserts the significance of Sellars’s place in the history of twentieth-century analytic philosophy. (shrink)

In the following dialogue between TT - a foundationalist - and WdeV - a Sellarsian, we offer our differing assessments of the principle for observational knowledge proposed in Wilfrid Sellars's 'Empiricism and the Philosophy of Mind'. Sellars writes: 'For a Konstatierung "This is green" to "express observational knowledge", not only must it be a symptom or sign of the presence of a green object in standard conditions, but the perceiver must know that tokens of "This is green" are symptoms of (...) the presence of green objects in conditions which are standard for visual perception.' In the ensuing dialogue, TT argues that it sets the bar too high when knowledge about perceptual conditions is required for ordinary observational knowledge - that young children, for example, are implausibly excluded as knowers given Sellars's principle. WdeV defends Sellars's metaknowledge requirement against these charges. Results from developmental psychology are surveyed for what they show about the actual capabilities of young children. The implications of these results for the success of Sellars's principle are debated. (shrink)

I argue that in “Empiricism and the Philosophy of Mind,” Wilfrid Sellars significantly misconstrued the early twentieth-century empiricists he was criticizing (empiricists such as Bertrand Russell, H.H. Price and C.I. Lewis). Because these philosophers and their theories were becoming passé (partly due to EPM itself but also due to broader trends), this misconstrual was not noted. As a result, Sellars’s most influential claim – that the given is a myth – did not receive the critical scrutiny that it should have (...) received prior to its widespread acceptance. (shrink)

Logical relativism is the view that a logical proposition is known just in case it is collectively endorsed in some culture. This striking and controversial view is defended by David Bloor and Richard C. Jennings. They cite in its support distinctive reasoning practices among the Azande as described by E. E. Evans-Pitchard. Jennings has challenged my critique of Bloor's logical relativism, claiming that my analysis is based on misunderstandings of Bloor and Evans-Pritchard. I argue that Jennings' clarifications of Bloor do (...) nothing to support the thesis of logical relativism, and that a direct examination of Evans-Pritchard's evidence suggests that the Azande reason just as we do.

I argue that we can achieve certainty about some empirical propositions. When someone is having a migraine and attending to it, she can be certain that she is in pain. I show that examples intended to undermine claims of certainty or to raise doubts about the reliability of introspection do not touch such cases. Traditional foundationalists have held that epistemically certain beliefs can serve as the basis for all one’s other justified beliefs. This is not so, because those beliefs that (...) are certain are spread too thinly to serve as broad justificatory foundations. Certainty has a different role. The best explanation for the existence of epistemically certain empirical beliefs is experientialism, the view that nondoxastic sensory experiences can justify beliefs. Experientialism then offers a framework for showing how the stream of sensory experiences can provide an adequate basis for the justification of our ordinary beliefs about the external world.

Jonathan barnes argues that heraclitus's unity of opposites doctrine is logically contradictory in that it requires the coinstantiation of contrary properties. but barnes relies on rather strained interpretations of the doxography. heraclitus's unity of opposites doctrine is better understood as consisting of two aspects: (1) a claim that opposing qualities, rather than being coinstantiated in one thing, are related to one another via a process of cyclic transformation; and (2) an attempt to illustrate the limited and incomplete perspectives through which (...) heraclitus believed humanity ordinarily viewed the world.

A dialogue between someone who finds Sellars's Rylean myth in "Empiricism and the Philosophy of Mind" quite implausible and another who defends it.

In order to provide an alternative to the Cartesian myth that knowledge of our thoughts and sensations is "given," Sellars posits a community of "Rylean ancestors" - humans at an early stage of conceptual development who possess a language containing sophisticated concepts about the physical world and about their own language and behavior, but who lack any concepts of thoughts or sensations. Sellars's presentation of this thought experiment leaves many important details sketchy. In the following dialogue, we offer our differing (...) assessments of how well those details could be filled out. TT questions how the Rylean hypothesis could provide a plausible account of human thought and sensory experience at any stage of human conceptual development. WdeV responds to TT's challenge by filling out the picture of what the Ryleans' conceptual world would look like. TT and WdeV debate the merits and the plausibility of the resulting picture.

Bernard Gert claims that the project of justifying morality is “the primary task” of his major work, Morality: Its Nature and Justification. However, the arguments for and the point of his justification are not entirely clear. Unfortunately, critical work on Gert’s theory of morality has not included detailed attention to his attempt to justify morality. Part I of this two-part essay offers a systematic examination and assessment of Gert’s justification. It is argued that Gert’s justification is successful, but limited in (...) its scope. (shrink)

Although Bernard Gert’s justification of morality is limited in what it accomplishes (as argued in Part I of this two-part essay), the deliberative structure he has set up in order to procure this justification is a quite fruitful one. With some modifications, this structure can be used to generate a significantly more powerful justification of morality than Gert’s. Part II of this essay shows how the moral system can be brought into direct engagement with common rejections of morality in a (...) way that Gert’s justification cannot do. It is shown how persuasive arguments can be brought to bear against these anti-moral alternatives and in favor of the moral system. (shrink)

In this engaging and accessible dialogue, four students offer contrasting arguments on the nature and scope of morality. While specific social policy issues, such as animal rights and racism, come into play, the discussions focus on more general--and fundamental--questions, including: Does morality limit personal freedom? Is morality relative to culture, or is it universal? What is the motivation to be moral? Is religion in tension with secular moral principles? Does science undermine morality? Can a common morality emerge out of the (...) diversity of human interests? A glossary of important terms and suggestions for further reading are included. (shrink)

Rorty's critique concentrates on one aspect of foundationalism: the claim that nonpropositional sensory awareness serves as the basis for propositional justification. This claim is an essential component of classical foundationalism, though not necessarily of the more moderate versions of foundationalism that have been proposed. Thus even if it were a successful critique it would tell against only one type of foundationalism. But nothing in Rorty's argument provides any reason to doubt the plausibility of a classical foundationalist explanation of why sensory (...) awareness justifies ordinary nonbasic propositions. Even classical foundationalism, then, remains untouched by Rorty's critique. (shrink)

Sydney Shoemaker offers an account of color perception that attempts to do justice, within a functionalist framework, to the commonsense view that colors are properties of ordinary objects, to the existence of qualia, and to the possibility of spectrum inversions. Shoemaker posits phenomenal properties as dispositional properties of colored objects that explain how there can be intersubjective variation in the experience of a particular color. I argue that his account does not in fact allow for the description of a spectrum (...) inversion scenario, and that it cannot sustain a functionalist relationship between an object's color and its phenomenal properties. Functionalists must, however, come to terms with Shoemaker's recognition that intersubjective spectrum shifts are possible. (shrink)

Bernard Gert’s account of morality is straightforward, clear and, in its essentials, easily grasped. As such, it offers rich pedagogical resources for teaching morality, not just in undergraduate courses but also in pre-college philosophy classes or workshops, including those offered during the elementary school years. Gert’s account, properly calibrated to the age group in question, can provide a unified framework for students to think about morality, clarify their understanding of it, and engage in discussions with each other about it. After (...) summarizing Gert’s account, I illustrate several ways in which it can be applied in the classroom, beginning with applications at the elementary school level and working up to pedagogy appropriate to high school and college. I conclude by considering and responding to some possible objections to this approach. (shrink)

In the intellectual autobiography that opens this book, Chisholm divides philosophers into “drones” and “commentators,” placing himself in the first group. As a drone, Chisholm proposed solutions to philosophical problems and asked his students and colleagues to try to refute him. He reports that they often did, sending him back to the drawing board. Chisholm’s wry self-description says much about his manner as well as his method. A more pretentious philosopher might have spoken of his dogged search for philosophical truth (...) in an age when many have come to disparage that quest. (shrink)

Julia Driver, Timm Triplett, and Kathleen Wallace challenge my account of moral arrogance, and Triplett and Wallace challenge its application to the problem of abortion. I try to show here that Driver's attempt to defend consequentialism from my charge that it promotes moral arrogance is successful only if consequentialism explicitly gives up what has been considered one of its major virtues. I acknowledge that Triplett has uncovered some unclarity in my claim that the moral acceptability of (...) abortion is an unresolvable moral issue. I also acknowledge that Wallace has uncovered some unclarity in my account of moral arrogance. After clarifying that account, I try to meet her challenge to defend my claim that it is not morally arrogant for a state to place some restrictions on abortions. (shrink)

Timm Triplett argues (Inquiry 29 [1986], no. 4) that David Bloor does not succeed in justifying a relativistic interpretation of mathematics. It is objected that Triplett has focused his attention on the wrong chapter of Bloor's Knowledge and Social Imagery, and that the examples which Triplett demands Bloor provide to make the case do appear in the subsequent chapter. Moreover, Bloor has anticipated and refuted Triplett's brief criticism of the examples that make Bloor's case for (...) the relativism of mathematics. Finally, Triplett's own example of a basic mathematical truth can be shown to be socially relative. (shrink)

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

Richard Rorty's philosophy is examined showing a strong move against analytic philosophy to a turn toward linguistic aspects of pragmatism.

In his early philosophy as well as in his middle period, Wittgenstein holds a purely syntactic view of logic and mathematics. However, his syntactic foundation of logic and mathematics is opposed to the axiomatic approach of modern mathematical logic. The object of Wittgenstein’s approach is not the representation of mathematical properties within a logical axiomatic system, but their representation by a symbolism that identifies the properties in question by its syntactic features. It rests on his distinction of descriptions and operations; (...) its aim is to reduce mathematics to operations. This paper illustrates Wittgenstein’s approach by examining his discussion of irrational numbers. (shrink)

To successfully transform Ender Wiggin from a bright six‐year‐old child into the most effective military strategist and space commander the world had ever known, teachers at the Battle School needed to teach him to discipline himself to think and behave like a soldier. In Ender's Game the International Fleet's Battle School subjected children to a rigorous and grueling educational program. This put the Battle School's administrators and teachers in an incredibly powerful position: they had the unilateral power to determine what (...) knowledge and skills were necessary to be a successful soldier. The work of French philosopher Michel Foucault is invaluable in showing how power and knowledge are interdependent in governing the I.F.'s soldiers and in teaching them to be self‐governing at the I.F.'s Battle School, which mirrors the Panopticon.

This article identifies problems with regard to providing criteria that regulate the matching of logical formulae and natural language. We then take on to solve these problems by defining a necessary and sufficient criterion of adequate formalization. On the basis of this criterion we argue that logic should not be seen as an ars iudicandi capable of evaluating the validity or invalidity of informal arguments, but as an ars explicandi that renders transparent the formal structure of informal reasoning.

Es wird gezeigt, dass Wittgenstein in seiner Frühphilosophie ein nicht-axiomatisches Beweisverständnis entwickelt, für das sich das Problem der Begründung der Axiome nicht stellt. Nach Wittgensteins Beweisverständnis besteht der Beweis einer formalen Eigenschaft einer Formel – z.B. der logischen Wahrheit einer prädikatenlogischen Formel oder der Gleichheit zweier arithmetischer Ausdrücke – in der Transformation der Formel in eine andere Notation, an deren Eigenschaften sich entscheiden lässt, ob die zu beweisende formale Eigenschaft besteht oder nicht besteht. Dieses Verständnis grenzt Wittgenstein gegenüber einem axiomatischen (...) Beweisverständnis ab. Sein Beweisverständnis bedingt ein Programm der Grundlegung der Mathematik, das eine Alternative zu den Ansätzen des Logizismus, Formalismus und Konstruktivismus darstellt. Wittgensteins Ansatz steht im Widerspruch zu den Ergebnissen der Metamathematik, da er die Möglichkeit der Formulierung von Entscheidungsverfahren in der Prädikatenlogik und Arithmetik voraussetzt. Um seinem Ansatz gegenüber der traditionellen Metamathematik Recht zu geben, müsste gezeigt werden, dass sein Beweisverständnis im Bereich der Logik und Arithmetik – der traditionellen Metamathematik zum Trotz – realisierbar ist.

This paper reveals two fallacies in Turing's undecidability proof of first-order logic (FOL), namely, (i) an 'extensional fallacy': from the fact that a sentence is an instance of a provable FOL formula, it is inferred that a meaningful sentence is proven, and (ii) a 'fallacy of substitution': from the fact that a sentence is an instance of a provable FOL formula, it is inferred that a true sentence is proven. The first fallacy erroneously suggests that Turing's proof of the non-existence (...) of a circle-free machine that decides whether an arbitrary machine is circular proves a significant proposition. The second fallacy suggests that FOL is undecidable. (shrink)

In vol. 2 of Grundlagen der Mathematik Hilbert and Bernays carry out their undecid- ability proof of predicate logic basing it on their undecidability proof of the arithmeti- cal systemZ00. In this paper, the latter proof is reconstructed and summarized within a formal derivation schema. Formalizing the proof makes the presumed use of a meta language explicit by employing formal predicates as propositional functions, with ex- pressions as their arguments. In the final section of the paper, the proof is analyzed (...) critically by applying Wittgenstein’s view on meta language, which does not lead to a questioning of the assumptions on which the proof is based but of its presumed use of meta language. Finally, it will be argued that determining if it is the undecidability proof or Wittgenstein’s analysis of meta language that is right depends on whether a decision procedure for a predicate that undecidability proofs have seemingly proven undecidable can nonetheless be defined. Thus serious attempts to define a procedure for such a predicate should not be ruled out without studying them. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Book Reviews 137 The Meanings of Landscape: Essays on Place, Space, Environment and Justice BY KENNETH R. OLWIG London: Routledge, 2019 REVIEWED BY TIMM SCHÖNFELDER Landscape is more than spatial scenery that meets the eye: it is an anthropogenic artefact, an intellectual construct, a mirror of culture; it even has its own language.1 This broadness is reflected in the compilation of nine authoritative essays by the geographer and (...) professor of landscape architecture Kenneth R. Olwig that were published during the past quarter of a century and are now molded into a more coherent whole. In this regard, the present volume can be considered the pinnacle of Olwig’s intellectual oeuvre. In a fervent foreword, the anthropologist Tim Ingold sets the tone when he urges the reader to shed the contemporary notion of what he terms “topophobia”—­ a lack of bond betweenpeopleandplaces—­andtoreinstatephilologyasacentralfield of interest after it was “relegated by techno-­ science to the margins of scholarship” (xv). To achieve this, the essays deal with an eclectic set of themes ranging from Ptolemy’s notion of “choros” as something similar to today’s understanding of landscape, to the humanistic geographer Yi-­Fu Tuan’s concept of “topophilia,” which is hailed as a guiding ideal for much of Olwig’s work. The articles are bound together by an introduction that quickly transcendsthegeometricallimitationsoflandscape,ontologicallyquestioning whether these can be representative of the world itself at all (3). The first chapter thus delves right into the etymologies of “landscape” and its historical implications in the Nordic countries and England with detours through Italy and the German lands. In a cursory, highly associative manner Olwig fathoms the respective cultural implications. Central is the idea that the concept of landscape is more than the mere scenicrepresentationofspaceitcametobeknownasinRenaissance art and culture.2 Rather, the Nordic variants of the word, like the Swedish landskap, are used to denote natural regions with their own polity that were then gradually subjected to a monarchic state, not least through the surveying and mapping of their territory (see also chapter two). ENVIRONMENT, SPACE, PLACE / VOLUME 13 / ISSUE 2 / 2021 138 At times, Olwig’s philological musings appear rather stretched, as when he associates the German word Grundgesetz (the “basic/­ fundamental law” of 1949, which until today serves as Germany’s constitution ) with a biopolitical dimension of “ground” as in “soil” (41).3 In cases like this, his use of literature is selective. This culminates in a problematic assessment of Nazi ideology as being motivated by a specific understanding of landscape. Statements like “there can be no doubt that the modern German conception of Landschaft was implicated in the promotion of blood-­ and-­ soil fascist ideology” (42) neglect important literature on the topic.4 Such generalizations are owed to the author’s sweeping tour de force approach. The reviewer would have preferred more guidance through the theoretical thickets by way of a clear, chronologically ordered argument. This is not helped by the occasional seeming inconsistency, as in the claim that the U.S. “inherited the British scenic idea of landscape” as a former colony while also being “very much the inheritor of German romantic ideas concerning the relation of culture to nature as expressed in the physical landscape” (45), which, in turn, showed parallels to “fascist landscapes” in the “attempt to cleanse geography of its environmentalist taint by making it a science of space” (42). This truly is a lot of ground to cover for one essay. The ensuing chapters, however, try to disentangle this inspired jumble. The second article, “Landscape, Place, and the State of Progress,” identifies a switch since the Renaissance from the idea of circuitous development to linear progress towards utopia. For Olwig, there is a “darker, Faustian side” to it that he identifies as the “dialectic of modernity,” which “opposes cosmic dreams of a utopian future to the topian exigencies of present and past”: to advance, the path had to be cleared of traditional elements (52). This materialized in courteous theatre as well as in Shakespeare’s popular plays, and in the new architecture of parks where landscape was symbolic for cultural and social progress (64). “Choros, place, and the spatialization of landscape” traces important theoretical threads within geography...

The semantics for counterfactuals due to David Lewis has been challenged by appealing to miracles. Miracles may skew a given similarity order in favour of those possible worlds which exhibit them. Lewis responded with a system of priorities that mitigates the significance of miracles when constructing similarity relations. We propose a prioritised ceteris paribus analysis of counterfactuals inspired by Lewis’ system of priorities. By analysing the couterfactuals with a ceteris paribus clause one forces out, in a natural manner, those possible (...) worlds which do not satisfy the requirements of the clause, thus excluding miracles. If no world can satisfy the ceteris paribus clause in its entirety, then prioritisation is triggered to select worlds that maximise agreement on those things which are favoured most. (shrink)

The random nature of immunoglobulin gene segment rearrangement inevitably leads to the generation of self‐reactive B cells. Avoidance of destructive autoimmune reactions is necessary in order to maintain physiological homeostasis. However, current central and peripheral tolerance concepts fail to explain the massive number of autoantibody‐borne autoimmune diseases. Moreover, recent studies have shown that in physiological mouse models autoreactive B cells were neither clonally deleted nor kept in an anergic state, but were instead able to mount autoantibody responses. We propose that (...) activation of autoreactive B cells is induced by polyvalent autoantigen complexes that can occur under physiological conditions. Repeated encounter of autoantigen complexes leads to the production of affinity‐matured autoreactive IgM that protects its respective self‐targets from degradation. We refer to this novel mechanism as adaptive tolerance. This article discusses the discovery of adaptive tolerance and the unexpected role of high affinity IgM autoantibodies. (shrink)
